Overview

This lecture provides a very cursory overview of marine chemistry. There are two fundamental ways
to view the chemistry of seawater: equilibrium vs. steady state. The concentrations of some
dissolved species can be explained
in terms of chemical equilibrium with marine sediments or the atmosphere. However, many chemical species in the oceans
appear to be at steady state concentrations far from equilibrium. We need to identify the chemical
sources and sinks to the ocean.

Objectives

You should be able to outline:

the main chemical sources and sinks to and from the ocean reservoir.

the difference between scavanged, conservative elements.
concentrations of trace metals.
